VectorShield

Check restaurant menus and medications for hidden mammal ingredients before you eat. Free safety lookups, built by someone who lives with AGS.

Alpha-Gal Syndrome reactions are delayed, invisible, and hard to trace. They start 3-6 hours after eating -- long after you've forgotten what was on your plate. VectorShield is a safety reference database for people with Alpha-Gal Syndrome: search medications, browse restaurants, and keep a personal log of meals and vitals in one place.

MEDICATION SAFETY DATABASE

Many common medications contain mammalian-derived inactive ingredients -- gelatin capsules, magnesium stearate, bovine-sourced collagen -- that do not appear on the label. VectorShield checks a curated database of medication ingredients to flag possible Alpha-Gal triggers so you can review them before you take them. Emergency medication lookups (EpiPen, epinephrine) are always free.

RESTAURANT SAFETY DATABASE

Browse 377+ restaurants and 8,400+ menu items with Alpha-Gal safety ratings. See cooking fat disclosures, cross-contamination notes, and community-sourced reviews from other AGS patients. Find safe dining options near you on an interactive map.

MEAL LOGGING AND VITALS TRACKING

Log meals by voice, text, photo, or barcode scan. VectorShield reads your heart rate and HRV from Apple Watch and displays trends alongside your meal log -- giving you a personal reference record to review at your own pace. All processing runs on-device via CoreML; your Apple Watch vitals are never sent to our servers and never sold.

COMMUNITY

Connect with other Alpha-Gal patients. Share restaurant reviews, post safe recipes, follow other members, and learn from people who understand what you're dealing with.

BUILT FOR EVERY SENSITIVITY LEVEL

Alpha-Gal Syndrome is not one-size-fits-all. Some patients only avoid red meat. Others react to dairy, gelatin, or even trace amounts in medications. VectorShield lets you set your sensitivity level (1-4) so food analysis, medication warnings, and personal context are calibrated to your specific situation.

APPLE WATCH COMPANION

The Watch app runs independently with voice-first meal logging, vitals tracking, restaurant search, and on-wrist notifications. Log a meal by speaking to your watch without pulling out your phone.

PRIVACY FIRST

Your Apple Watch health data is processed on-device using CoreML and is never sent to our servers or sold. VectorShield does not track you and does not require an account for core safety features.
